Embedded dynamic configuration assignment for unprotected remote terminal unit (RTU)

A non-transitory computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• receiving, by a dynamic remote terminal unit (RTU) configuration assignment server (DRCAS) in a supervisory control and data acquisition system (SCADA) network, an RTU configuration request to configure an RTU in a “raw” condition residing a location remote from the DRCAS, wherein the RTU is pre-configured with an embedded remote configuration assignment capability;
• establishing, by the DRCAS through an initial data communication relay (IDCR) apparatus, a low-level communication channel with the RTU using a low-level communication protocol and the embedded remote configuration assignment capability, wherein the low-level communication protocol uses a tri-frequency encoding scheme;
• authenticating the RTU configuration request and an identity of the RTU using one or more of Network Access Control (NAC) and site occupancy sensors;
• assigning, by the DRCAS through the IDCR, a SCADA Communication Protocol (SCP) address for the RTU, the SCP address supporting a high-level communication channel;
• connecting, by the DRCAS using the high-level communication capability, the RTU to the SCADA network;
• and
• configuring, by the DRCAS using the high-level communication capability, the RTU for use in the SCADA network.

A computer-implemented system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• receiving, by a dynamic remote terminal unit (RTU) configuration assignment server (DRCAS) in a supervisory control and data acquisition system (SCADA) network, an RTU configuration request to configure an RTU in a “raw” condition residing a location remote from the DRCAS, wherein the RTU is pre-configured with an embedded remote configuration assignment capability;
• establishing, by the DRCAS through an initial data communication relay (IDCR) apparatus, a low-level communication channel with the RTU using a low-level communication protocol and the embedded remote configuration assignment capability, wherein the low-level communication protocol uses a tri-frequency encoding scheme;
• authenticating the RTU configuration request and an identity of the RTU using one or more of Network Access Control (NAC) and site occupancy sensors;
• assigning, by the DRCAS through the IDCR, a SCADA Communication Protocol (SCP) address for the RTU, the SCP address supporting a high-level communication channel;
• connecting, by the DRCAS using the high-level communication capability, the RTU to the SCADA network;
• and
• configuring, by the DRCAS using the high-level communication capability, the RTU for use in the SCADA network.
